Co-Work™
Co-Work™ is a six function networking feature that is built into every Advanced M52 controller. Through the use of a three
wire telephone cable you can link up to 16 units with up to 32 compressor circuits on one local area network. What this does
is it makes all units in the network operate as one system which improves the system performance, reliability and
manageability

Control Redundancy
Co-Work™ allows multiple master units to coexist on the same network. In case any master requires service the remaining units
will automatically take over control of the whole system. In the event of a controller failure control will be transferred
automatically to the other masters minimizing loss of system control and down time.
Expansion of Control Steps
Co-Work™ improves the system performance by utilizing the limited number of control steps in individual units and converts them
to a maximum of 16 steps. This provides more precise control and limits on/off cycles by matching capacity to load
P R O D U C T

Co-Work™
Two Levels of Duty Sharing.
The first level maintains the required number of duty units in the network and automatically sequences duty and redundant
units on to even out run time. This function is time based and is factory set for 24hrs. This value is adjustable.
The second level of duty sharing automatically initiates lead/lag sequence of the components among the duty units to
equalize run time.
Data Synchronization.
Unit operation data such as set points, time schedule, alarm status (see Setting Summary page for list of synchronized data)
is synchronized among units under the same Co-Work™ network.
Sequential Load Activation.
Co-Work™ coordinates the activation and deactivation of components in a unit and within a group of units to minimize in-rush
current.
Control Value Averaging
Co-Work™ exchanges sensor reading of temperature and humidity of network units and operates from the average reading.
This prevents units from fighting each other when multiple units control one space.

P R O D U C T

Co-Work™
Settings Menu, Sensor mode:
Additional flexibility in configuring a ‘n+1’ Co-Work network has been added. In certain cases it could be desirable to ignore
the sensor data from standby units. Therefore, the client may now select to ignore or include sensor data from standby units.
In the factory default setting, the Advanced M52 will ignore sensor data from a standby unit in the calculation to determine
the average return air temperature and humidity in the controlled space. To include sensor data for standby units, open page 6
of the Settings section and review the Sensor mode entry. To include the sensor data of a standby unit in calculating the
average return air temperature and humidity for a space, select REMOTE option instead of LOCAL.

representative or the factory for details.
The number of duty units will be established by the controller based on the cooling demand. The number of duty units
on page three of the settings tab can be adjusted manually if required.
